Features 

Analog Bargraph display 

Visual indication of measurement in the tradition of an analog meter 
pointer. The bargraph consists of 52 discrete viewing segments. The 
bargraph is useful for detecting faulty contacts, identifying 
potentiometer gradations, and viewing signal spikes. 

True RMS vs. Average Sensing (AC Measurements) 

True RMS meters can accurately measure non-sinusoidal waveforms, 
as well as distorted sine waves that contain harmonics. Average 
Sensing is a fast, accurate and cost effective method of measuring 
pure sine wave signals. However, non-sinusoidal waveforms cannot 
accurately be measured using Average-sensing techniques. 

Backlit display 

The MultiLog™ is equipped with a backlight for viewing the LCD 
display in poorly lit areas. 

Data Hold 

The 

HOLD

 function freezes the reading on the display for later 

viewing. 

Manual and Automatic Ranging 

The MultiLog™ series multimeters are Autoranging, with manual 
override. 

Smart Power Auto Power Off 

Smart Power shuts the meter down automatically after approximately 
17 minutes of inactivity.  

Audible Beeper 

To disable the audible meter tones, press and hold the Hz key while 
powering the meter. 

Automatic Test Lead Resistance Compensation 

Automatically compensates for the resistance of the test leads, as well 
as the internal protection circuitry automatically, ensuring greater 
accuracy of low resistance measurements. 

Datalogging 

The MultiLog™ series of multimeters store reading for review on the 
LCD display or downloading to a pc using the supplied software.
